| Subcellular Location | Extracellular (secreted) |
| Function | It functions as an endoxylanase (EC 3.2.1.8) preferentially cleaving long-chain, water-insoluble oligoxylosides. Sequential action of xylanases B and A leads to efficient hydrolysis of xylan producing xylotriose, xylobiose and xylose. |
| Glycosylation Status | |
| Technique(s) used for Glycosylation Detection | Periodic acid-Schiff (PAS) staining |
| Protein Glycosylation linked (PGL) gene(s) | |
| Additional Comment | Xylanases from S. lividans IAF18 and IAF42 clones are glycosylated. |
